Roux-en-Y Gastric Bypass

This works by creating a small pouch. That is closed off from the rest of the stomach to make you feel fuller faster. It also involves re-routing your small intestines, which makes the food bypass part of the small intestine. This is both a restrictive and malabsorptive operation. Patients who have the gastric bypass lose an average of 80-85 percent of their excess body weight in 18 months.
